Ray floret color can fade with time, both in the field and on dried specimens, making it difficult to distinguish Solidago hispida from S. bicolor, in which it has sometimes been included. The latter tends to have slightly broader phyllaries and more obviously clavate pappus bristles. The two co-occur in some populations but do not appear to form hybrid swarms with a range in ray corolla color. Three varieties have been described on the basis of growth and pubescence features and are sometimes recognized. These may represent only extremes in continua of variation. Variety lanata has densely villous stems and leaves; such plants occur scattered through much of the range of the species. Two glabrous-stemmed varieties have been described; plants of var. tonsa are relatively small and were first described from Newfoundland; var. huronensis includes relatively tall glabrous plants found growing in sand dunes along the shore of Lake Huron in Michigan and Ontario. The latter plants have been treated as var. tonsa but the name is misapplied. Other varietal names are based on minor variations.
